Our Gen 3 & Gen 4 LS1 Header Flanges are ideal for the enthusiast building their own headers for their N/A, Turbocharged, or Supercharged combo. CNC Laser Cut from a 3/8" thick 304 SS flange, these are thick and sturdy enough to resist warping and provide a quality flange for your build. These flanges have a hole big enough to give a few thousandths clearance when using 1.875" tubing.
